This report discusses the maintenance and operation of a wind turbine generator that has been undergoing tests as a source of energy for remote Coast Guard lighthouses. The report documents both the effects of operating the wind machine in the marine environment and the maintenance that it required. Design parameters and performance records of the generator are also evaluated. The HR2 is a horizontal axis, upwind oriented, three bladed wind machine. It is equipped with a direct drive system that allows the kinetic force captured by the propeller to be converted directly into rotational force driving the main shaft. The HR2 alternator and blade/hub system are allowed to tilt out of a near-vertical plane about a shaft and bearing mechanism. The VARCS is a torsion spring and hinge mechanism that acts against the lifting dynamics of the spinning blades. As high winds or gusts tilt the alternator about the hinge, the VARCS's spring opposes this force and regulates the blades angle of attack into the wind; the propeller's RPM drop when tilted because of the feathering action. If the wind subsides, the force of the VARCS spring drives the alternator assembly down and presents the blades back into the wind.period shows the Avery Point test site to be just outside of the measured l0 to 30 mph window during the sample period. Diurnal variations are wide as indicated by the instantaneous samples. Figure 7 reinforces the power ...
